The first DLC for DA2 is coming out, and it looks like you'll get to leave Kirkwall. With luck, you'll get new maps, too:

The announcement tells you to "Leave Kirkwall", and explore a prison constructed by the Grey Wardens. You will have to foil a criminal cartel that's taken a violent interest in the Hawke family lineage. The expansion promises several new locations, Darkspawn enemies, a new class specific weapon and more achievements.
